he was honorably discharged from the u.s. navy reserve just last friday after ten years service, including a tour in the persian gulf. was that the trigger for this killing spree? or evidence of careful planning? >> i have more questions than i do have answers at this point. >> reporter: if dorner gets his wish, if he is killed, we might never know the whole truth. nick watt, abc news, los angeles. >> wow. and this 6,000 word manifesto gives some scary insight into what he's thinking. one part in the document where he writes, self-preservation is no longer important to me. i do not fear death, as i died long ago on 1-2-09, referring to the day he was fired. so this is a guy that is looking to kill and be killed. that's what makes him interesting. >> this manifesto is interesting. he switches from being insane to 100% lucid. he talks about, in two different political figures and different stars on television. almost like this is something that he now has a platform. and unfortunately he does, because this is such a big story.
